Savings calculator

Estimate your savings

Tell us about your roof and your bill, and see a rough system size, what it could make and save, and how long it might take to pay for itself. It’s an estimate; the free survey gives the real figures.

An estimate, not a quote or a promise. Real figures depend on your roof, shading, the weather, energy prices and how you use power, and come from the free survey.

What the estimate assumes
  • Electricity at £0.27 a kWh
  • Export paid at £0.15 a kWh
  • 950 kWh a year per kWp on a south roof
  • Typical prices from our solutions pages

For a quote, tell us

  1. Your address, so we can look at the roof from above
  2. Roughly what you pay for electricity a year
  3. What you’d like: panels, a battery, a charger, a heat pump
  4. Anything we should know: a listed building, a tricky roof, a date to work to
Village rooftops from above, grey slate and red tile, several south-facing slopes covered in neat rectangles of black solar panels

Questions

How accurate is the calculator?

Close enough to tell whether solar is worth a survey. It doesn’t know about shading, your exact roof or your tariff; the survey and our MCS figures do.

Why is the battery estimate higher?

A battery keeps the sunshine you don’t use at midday for the evening, so you buy less from the grid. It also costs more, which is why the payback can be longer.

Is a quote really free?

Yes. The survey, the design and the written quote cost nothing and commit you to nothing.
